Abstract: An electrode assembly manufacturing method includes the steps of: assembling an electrode stack; performing a primary heat press operation on the electrode stack; then performing a pre-heating operation on the electrode stack; and then performing a secondary heat press operation on the electrode stack. The pre-heating operation may include applying heat and pressure to the electrode stack for a time period from 10 seconds to 40 seconds under a pressure condition from 0.5 MPa to 2 MPa and under a temperature condition from 50° C. to 85° C. The pressure condition applied in the pre-heating operation may include applying a lower pressure than that applied in the primary and secondary heat press operations. The primary heat press operation may include engaging the electrode stack with a gripper to secure a position of the electrode stack, which gripper may be disengaged from the electrode stack before performing the pre-heating operation.
